Good fixes and a great showcase. Thank you.

That array.filter was so frustrating at the moment. So glad they finally fixed that.

The dumb filter intellisense always annoy me, this is the greatest change in a while.

finally filter works as expected, thanks for the video 👍

thanks for sharing.

Damn, that's so sick. I always wished for this, but wasn't holding my breath- what a nice surprise.

Filter type inferences I have been wanting for as long as i have used typescript, especially with JSDoc where you can't directly say Object is Type, I am going to be updating so quickly when this comes out I can't wait

Yeah filter type inference is a gamechanger.

couldn't one just make an extension himself?

Holy 🐄 I've been figuring these issues a lot lately

It is why I learnt reduce method. Always bothered me that I had to filter array, then map it, and then add type checks again because it forgets which type it should be.

I'm so happy to know I won't need `.filter((data): data is Exclude => !!data)` anymore!

Great explanation mate!

Nice. I hit this problem all the time.

fuck yeah, digestible typescript news, let's go ;-)

what if obj[key] return another object the next time you call it after the check?

For the constant index accesses, it seems very helpful, but will that really be okay? Sure the regular indexing won't cause any side effects, but proxies exist! It'd be severe abuse of notation, but theoretically `proxy[key]` needn't return the same value, or even the same type of value both times, right? Will TypeScript be able to understand this, or will we be able to tell it that explicitly somehow? Or is this just broken with no fix?

So it got a string instead of a "schtring" - great. And more awesome, typescript finally recognizes types !! Then i bailed out.

Finally, this feature was way overdue.

I have this filter issue ALL the time

Hope it doesn't make typescript slower than it already is.

Nice showcase ty! Sidenote: you should really put some effort to learn how to properly touch type, its painful to watch

I actually can, but my current setup uses a wave arm mic which goes right across the centre of my keyboard… Need to get an overhead mic arm!

wow a programmer who doesn’t know blind typing? first time for everything, I guess good content though, even if a bit too lengthy

@JollyCoding

Someone else mentioned this, it’s more that my mic arm is low profile and goes across the centre of my keyboard so my hands hit it when typing. Need to get an overhead one

Do people actually use TypeScript?...

I can't build a production app without typescript these days. When I think of the future. But we have to do a complete rewrite after a few years

If you want to build fast and don't care about types then I guess you just go with js but I originally started with C# and enjoy types so I only use typescript.
